Bond Prices Make Noise, but Income Drives the Returns

The Price Is Noise. The Income Is the Return.

Every time rates jump, the headlines follow the same script: bonds got hit. On a statement, they did. But that framing confuses two very different activities. Trading bonds is about where prices go next. Investing in bonds is about building a portfolio that pays you income for as long as possible. For investors, the price move is the least important number on the page.

Take a five-year bond yielding 4.5%. Its price sensitivity to rates, also known as duration, is roughly 4.4, so a one percentage point rise in yields knocks about 4.4% off its value. Now compare that to what it pays: 4.5% per year, every year, on average. One year of income covers the damage from a full point rise in rates. Over five years, the bond delivers roughly 22.5% in income, and because a bond held to maturity returns its full face value, the paper loss works its way back anyway.

Bond funds and exchange-traded funds (ETFs) don’t mature, which can make investors nervous because there’s no maturity date pulling the NAV back toward par. But the same basic math still applies, just through a different mechanism. As bonds mature, funds reinvest the proceeds at prevailing yields. When rates rise, NAVs fall initially, but the portfolio’s income stream begins to rise as well. Over a holding period roughly equal to the fund’s duration, that higher income can help offset the initial price decline. Consider the Bloomberg Aggregate Bond (Agg) Index, which has generally had a duration of roughly six to seven years over the past decade. During that period, starting yields and subsequent seven-year returns have had a correlation of around 94%. The relationship isn’t perfect, in part because index rules require bonds with less than one year to maturity to roll out of the index, but the message is clear: starting yields have historically been a powerful indicator of longer-term bond returns. And there’s a simple reason why. Over time, income, not price movement, has been the predominant driver of fixed income returns.

This is why rising rates are not the enemy of an income investor. They are a raise. Every interest payment and every maturing bond gets reinvested at higher yields, lifting the income stream you'll collect for years to come. The goal isn't to avoid ever seeing a red number. It's to keep the income coming, and keep it growing, for as long as you can.

History backs this up, though past performance does not guarantee future results. Over the past several decades, income has accounted for the vast majority of the Agg’s total return. Prices swung year to year but largely netted out. The income compounded.

2022 is the exception that proves the rule. The bond market lost about 13%, its worst year on record, and many fund investors watched NAVs fall by double digits. But the market started that year yielding under 2%, with no income cushion to absorb the shock. Today, with yields in the 5% to 6% range, that cushion is two to three times larger.

Price moves matter if you need to sell next month. But investors typically don't own bonds to sell them next month. They own them to fund future spending, steady a stock-heavy portfolio, and generate potential cash flow. So when the next rate scare hits, look past the price and the NAV and ask what you're getting paid, and for how long. At current levels, the answer is a lot. That's the number that compounds.
